Narrative:

Departed msp at AM37, runway 29R. We were handed off to departure control on 124.7 and given a clearance 'turn left 190 degree heading, climb and maintain 17000 ft.' the first officer was flying, so I read back the clearance and set 17000 ft in the awi. The first officer verified this setting as per air carrier SOP's. On the 190 degree heading, I saw traffic at 12-1 O'clock at 3 mi. A short time later, we got a TA from TCASII. I could see we were on a converging course, so I took the aircraft, pushing it over and about 45 degrees of bank. After I started this maneuver, we got an RA from TCASII 'decrease rate of climb.' at 1 point during the RA, I saw the traffic at 900 ft on TCASII. The other aircraft was an large transport. He should have been restr above us or we below him.

Title: AN ACR MLG RESPONDED TO A TCASII ALERT.

Narrative: DEPARTED MSP AT AM37, RWY 29R. WE WERE HANDED OFF TO DEP CTL ON 124.7 AND GIVEN A CLRNC 'TURN L 190 DEG HDG, CLB AND MAINTAIN 17000 FT.' THE FO WAS FLYING, SO I READ BACK THE CLRNC AND SET 17000 FT IN THE AWI. THE FO VERIFIED THIS SETTING AS PER ACR SOP'S. ON THE 190 DEG HDG, I SAW TFC AT 12-1 O'CLOCK AT 3 MI. A SHORT TIME LATER, WE GOT A TA FROM TCASII. I COULD SEE WE WERE ON A CONVERGING COURSE, SO I TOOK THE ACFT, PUSHING IT OVER AND ABOUT 45 DEGS OF BANK. AFTER I STARTED THIS MANEUVER, WE GOT AN RA FROM TCASII 'DECREASE RATE OF CLB.' AT 1 POINT DURING THE RA, I SAW THE TFC AT 900 FT ON TCASII. THE OTHER ACFT WAS AN LGT. HE SHOULD HAVE BEEN RESTR ABOVE US OR WE BELOW HIM.
